Cross-border regions are characterised by many inherent challenges. Such challenges can include differences in languages, cultures, currencies, markets, labour market conditions, political visions and priorities, governance structures – to name but a few. Greater Copenhagen1 is no different in terms of the challenges it faces as a cross-border region.The aim of this study is to investigate the pos
The optical spectra of a quantum cascade laser structure under nonequilibrium conditions is studied using the technique of nonequilibrium Green functions. We focus on the impact of Coulomb corrections and their dependence on the operating conditions. The role of the static mean field due to the charge distribution by electrons and ioninzed donors is investigated.
Continuously indexed Gaussian fields (GFs) is the most important ingredient in spatial statistical modelling and geo-statistics. The specification through the covariance function gives an intuitive interpretation of its properties. On the computational side, GFs are hampered with the "big-n" problem, since the cost of factorising dense matrices is cubic in the dimension. Although the computational
Popular Abstract in Swedish Tillväxtfaktorer påverkar signaler mellan celler i hjärnan Människors hjärnor innehåller flera miljarder hjärnceller, vilka är förutsättningen för vårt beteende, våra känslor och våra tankar. Hjärncellerna bildar kontakter, synapser, med varandra. Genom dessa överförs signaler från en cell till en annan. Varje cell kontaktar en mängd andra celler, både sådana med liknanThe neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. Such plasticity is believed to be a cellular correlate for important processes like learning, but also for diseases, for

Popular Abstract in Swedish Byggnadsprestanda – Metoder för förbättrad prediktering och verifiering av energianvändning och inneklimat Hans Bagge, Byggnadsfysik LTH Introduktion För att kunna minska utsläpp av växthusgaser och rädda klimatet på jorden är det av yttersta vikt att vi kan bygga byggnader med låg energianvändning och bra inneklimat. Byggnader står i dagsläget för mellan 30 och 40 %Reducing CO2 emissions is one of the most important goals in Europe as well as the rest of the world. To reach that goal, the use of energy must be reduced. Thus, the building industry is facing a great challenge. Not only energy efficiency but also sustainability is desirable in the building stock. This thesis presents and suggests methods that can be used to improve prediction and verification o
The design and fabrication of a home-made thin-layer electrochemical flow cell are reported. The performance and electrochemical characteristics of thin-layer cells are evaluated in terms of flow rate and channel thickness. The adaptability of the flow cell for amperometric and electrochemiluminescence measurements is demonstrated. Also, a flow injection method comprising electrochemical generatio
The aim of this thesis is to describe and analyse Swedish-German contacts in medicine 1933-1945. It shows how the National Socialist German Physicians’ Federation (NSDÄB) tried to strengthen connections with the Swedish medical profession and academic medicine and to spread NS-propaganda to carefully selected Swedish physicians. The dissertation consists of four papers. In the first paper the inte
We present a Bayesian ideal observer model that estimates observer translation and rotation from optic flow and an extra-retinal eye movement signal. The model assumes a rigid environment and noise in velocity measurements, and that eye movement provides a probabilistic cue for rotation. The model can simulate human heading perception across a range of conditions, including: translation with simul
In this study, we demonstrate that an integrated approach, combining palaeolimnological records and limnological monitoring data, can increase our understanding of changing ecological patterns and processes in shallow lakes. We focused on recent regime shifts in shallow Lake Krankesjon, southern Sweden, including the collapse of the clear-water state in 1975 and its subsequent recovery in the late
The human rights regime and the trade regime set obligations on states that may create conflicts that challenge a state’s autonomy for policy and regulatory practices. To deal with these conflicts, we argue that states employ different causal mechanisms from Risse, Ropp and Sikkink’s spiral model when setting their commitments to, and executing compliance with, these regime obligations, and that t
The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions
Computational models play an increasingly vital role in scientific research by enabling the numerical simulation of complex processes. Such models are also fundamental in geosciences. For instance, they offer critical insights into the impacts of global change on the Earth system today and in the future. Beyond their value as research tools, models are also software products and should therefore a
How environmental and climate challenges that often evoke strong negative emotions are communicated and responded to is of great importance. These include forest fires, plastic pollution and flooding that can produce fear, sadness and powerlessness. Images are important to this communication, yet how these challenges are captured through visual communication tools and to what outcomes requires fur
We present PyeLink and SyeLink, two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink eye tracking hardware. PyeLink simplifies experiment creation through plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) while enabling two features not available in existing tools: recording data during calibrati

Since 1978, China has experienced a series of economic reforms, transitioning from a centrally planned economy to a liberal market economy. Correspondingly, the economic transformation has left a profound impact on the health care system. Universal free health care provided by state-owned enterprises was gradually replaced by modern social medical insurance schemes. The government dramatically dec
